The Death of Bucky Barnes.
It was one of the greatest moments in Zemo family history: America's living legend cast into the icy depths, lost in suspended animation for over a generation, his sidekick killed in the red glare of a rocket's explosion. And laughing all the while, the man who made it all happen: Baron Zemo. It was a legend that sustained the father in his many unholy crusades of evil. And, after his passing, the legend ennobled the son to aspire to even greater achievements in the Zemo name. But like many legends, it was not fully true. And now that the young Baron Zemo has found out the truth, the world is not safe from his mad plans to make it true.
